Description

  The present invention relates to a spreader machine mounted on a traveling machine body.

  The conventional spraying machine is to disperse powder materials and pellets such as fertilizer and chemicals on the farm scene while moving by attaching a spraying device to the rear side or front side of the traveling machine body such as a tractor, The spraying device includes a hopper that stores an object to be sprayed such as fertilizer, a feeding device that is provided at the bottom of the hopper, and a spraying hose that is connected to a lower portion of the feeding device.

  The feeding device in the spraying device described above includes a feeding roll that is rotationally driven by an electric motor or the like. The hopper bottom discharge port is provided with a shutter that can be opened and closed, and fertilizers such as fertilizer that fall from the bottom discharge port that is opened by opening the shutter are subject to rotation of the feed roll. It is fed to the spray hose with the set feed amount (see Patent Document 1 below).

  In the conventional spreader, when the spreader is mounted on the front side of a traveling machine such as a tractor, the frame supporting the spreader hose holds the lower part of the spreader hose at a position close to the ground. After the work was finished, when the traveling aircraft tried to get over the kite in the same state, there was a problem that the frame holding the lower part of the spray hose collided with the kite. For this reason, it is necessary to remove the frame that holds the lower part of the spray hose from the traveling machine body before the traveling machine body gets over the kite, which takes time and effort.

  The present invention has been proposed to deal with such problems. In other words, in a spraying machine that works by attaching a spraying device to the front side of the traveling machine body, it is possible to eliminate the trouble of removing the frame that supports the spraying hose in advance when the traveling machine body gets over a kite etc. It is a problem.

In order to solve such a problem, the present invention has the following configuration.
A spraying device comprising a hopper for storing a sprayed object, a feeding device attached to a bottom portion of the hopper, and a spraying hose for guiding the sprayed material fed by the feeding device to the vicinity of the ground. A spraying work machine that supports and spreads the traveling machine body while moving, and includes a frame that supports the spraying device on the front side of the traveling machine body, and the frame has a lower part of the spraying hose close to the ground A spraying work machine characterized in that a holding arm for selectively holding a position and a position away from the ground is connected.

  In the spraying machine of the present invention having such a feature, the lower part of the spraying hose can be easily separated from the ground by switching the holding state of the holding arm, so that the traveling machine body gets over the kite etc. In this case, it is possible to save the trouble of removing the frame supporting the spreading hose in advance.

It is explanatory drawing which showed the spraying work machine which concerns on embodiment of this invention. Explanatory drawing explaining the switching mechanism of the holding | maintenance position of a holding | maintenance arm (state which hold | maintains the lower part of a spraying hose in the position close | similar to the ground). Explanatory drawing explaining the switching mechanism of the holding position of a holding arm (Description of operation which hold | maintains the lower part of a spraying hose in the position away from the ground). Explanatory drawing explaining the switching mechanism of the holding position of a holding arm (Description of operation which returns the lower end part of a spraying hose to the position close | similar to the ground).

  Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same function, and repeated description in each drawing will be omitted as appropriate.

  As shown in FIG. 1, a spreading work machine 1 </ b> A is a work in which a spreading device 1 is attached to the front side of a traveling machine body T such as a tractor, and a spreading object such as fertilizer is spread on a farm field while traveling on the traveling machine body T. Is to do.

  The spraying device 1 mounted on the traveling machine body T includes a hopper 2 for storing a sprayed object such as fertilizer, and a feeding device 3 mounted on the bottom of the hopper 2. A distribution funnel 4 to which a spray hose 5 is connected is detachably mounted.

  The spreading device 1 is supported on the front side of the traveling machine body T via a frame F (vertical frame F1 and horizontal frame F2). Moreover, the lower part 5A of the spraying hose 5 of the spraying device 1 is held by the holding arm 10, and the holding arm 10 selects the lower part 5A of the spraying hose 5 at a position close to the ground GL and a position away from the ground GL. It is connected to the frame F via the holding plate 11 so as to hold it.

  According to such a spraying work machine 1A, when the traveling machine body T travels in the field and performs the spraying work, the lower 5A of the spraying hose 5 in the spraying apparatus 1 is held at a position close to the ground GL. When the traveling machine body T gets over the kite, the lower part 5A of the spray hose 5 is held at a position away from the ground GL.

  According to this, since the holding position of the lower part 5A of the spray hose 5 can be easily changed before the traveling machine body T gets over the kite, it is possible to save the trouble of removing the frame supporting the spray hose 5 in advance. . Further, after that, when entering the field again and performing the work, the position of the lower portion 5A of the spray hose 5 can be switched to a position close to the ground GL, so that the work can be easily continued even when the work is continued. can do.

  2 to 4 show the holding position switching mechanism of the holding arm 10 described above. The holding arm 10 is pivotally supported by the frame F via a holding plate 11, and the holding plate 11 includes cam holes 12 that hold the holding arm 10 at different angles. When holding the lower portion 5 </ b> A of the spray hose 5 at a position close to the ground, the holding plate 11 is fixed to the frame F by a lock pin 13 as shown in FIG. 2. At this time, the cam pin 12A is held on the front side of the cam hole 12 bent in a U-shape.

  In order to hold the lower portion 5A of the spray hose 5 at a position away from the ground, first, the lock pin 13 described above is removed to make the holding plate 11 rotatable around the shaft 11A, as shown in FIG. Hold the lower part of the holding arm 10 by hand and lift the lower part 5A of the spray hose 5 upward. By this operation, the cam pin 12A inserted into the cam hole 12 of the holding plate 11 moves to the rear side of the cam hole 12, and the cam pin 12A is fitted to the rear of the cam hole 12 to hold the cam pin 12A. The arm 10 is held at the inclination angle shown in FIG.

  Again, in order to hold the lower portion 5A of the spray hose 5 close to the ground, the holding plate 11 can rotate around the shaft 11A by lifting the cam pin 12A and moving it to the front side of the cam hole 12. It becomes a state. In this state, hold the lower part of the holding arm 10 by hand, lower the lower part 5A of the spray hose 5, bring the holding plate 11 closer to the frame F, and align the lock hole 13A of the frame F with the lock hole 13B of the holding plate 11 Then, the holding plate 11 is fixed by inserting the lock pin 13 there.

  According to such a spraying work machine 1A, by switching the holding state of the holding arm 10, the lower part 5A of the spraying hose 5 can be easily separated from the ground. In this case, it is possible to save the trouble of removing the frame supporting the spreading hose 5 in advance.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the gist of the present invention. Even if it is included in the present invention
